TO CONNECT AN EXTERNAL 12 VDC POWER SUPPLY:
The standard
Quick Assist II
may be used with an external
12 VDC power supply. Optional items are not supplied.
Instructions:
1. Remove the
Quick Assist II electronics from the
housing.
2. Carefully drill or punch a 0.484" hole in the bottom of
the
Quick Assist II
enclosure.
3. Route the power supply cable trough the
Ritron
#02500127 strain relief
fitting. (not supplied)
4. Use
Ritron #RPS-203 Power Supply (not suplied),
11-15 VDC, 200mA
, or equivalent, to power the Quick
Talk. The
Quick Assist II
requires 11-15 VDC, 150 mA
minimum.
5. Connect the positive (+) terminal of the power supply
cable to the
+EXT. PWR
screw terminal on the
Quick
Assist II
, refer to FIG-6.
6. Connect the negative (-) terminal of the power supply
cable to the
-EXT. PWR
screw terminal on the
Quick
Assist II
, refer to FIG-6.
NOTE: When programming,
use either fresh Alkaline
batteries (or an external power supply), to power
the
Quick Assist II
.
When programming is
finished,
you may either insert Ni-Cd batteries
or leave Alkaline batteries in place.
WARNING: DO NOT attempt to charge Alkaline
batteries from an ex12VDC
power supply.
When powering Quick Assist II with ALKALINE
BATTERIES
, set J103 as follows to disconnect the
charging current paths:
a. To set the
Quick Assist II
for use with alkaline
batteries, move Jumper J103 to cover only one pin of
the jumper base, as shown in FIG-5; this setting
prevents the flow of charging current.
b. Dial
"943"
to program the
Quick Assist II
for use with
alkaline batteries.
When powering Quick Assist II with NI-CD BATTERIES
,
set J103 as follows to connect the charging current
paths:
c. Cover both pins with Jumper J103, as shown in FIG-
5, to charge the Ni-Cd batteries from the External
Power connection.
d. Dial
"944"
to adjust the Quick Talk voltage; the unit
then transmits a "Low Battery" phrase.
NOTE: Because Ni-Cd batteries self-discharge rapidly,
you must constantly charge them with an
ex12VDC power.
